Today will discuss the basic concept and simplest way to how to reverse a number in c++ by programming and how to make program for reverse of a number without array in c++ programming. How to how to count number of digit in a number in c++ programming.
Today will discuss the basic concept and simplest way to how to reverse a number in c++ by programming and how to make program for reverse of a number without array in c++ programming. How to how to count number of digit in a number in c++ programming.
Write a program to reverse a number
#include
using namespace std;
int main()
{
int n, r=0,d;
cout<<“Enter the number=”<
cin>>n;
cout<<“Number befour reverse= “<
while(n>0){
d= n%10;
r= r*10+d;
n=n/10;
}
cout<<“Number After reverse= “<
return 0;
}
using namespace std;
int main()
{
int n, r=0,d;
cout<<“Enter the number=”<
cout<<“Number befour reverse= “<
d= n%10;
r= r*10+d;
n=n/10;
}
cout<<“Number After reverse= “<
}
Output:
Enter the Number= 1234
Number befour reverse= 1234
Number After reverse= 4321
Number befour reverse= 1234
Number After reverse= 4321
program to count no of digit of a number
#include
using namespace std;
int main()
{
int n, c=0,d;
clrscr();
cout<<“Enter the number: “<
cin>>n;
while(n>0){
d= n%10;
n=n/10;
c++;
}
cout<<“The enter number have”<< d <<“digit”;
return 0;
}
using namespace std;
int main()
{
int n, c=0,d;
clrscr();
cout<<“Enter the number: “<
while(n>0){
d= n%10;
n=n/10;
c++;
}
cout<<“The enter number have”<< d <<“digit”;
return 0;
}
Output:
Enter the Number: 1234
The enter number have 4 digit
The enter number have 4 digit
